Glyceryl P-Aminobenzoate (Glyceryl PABA) UV Protective Sunscreen Raw Material-CAS 136-44-7

Glyceryl P-Aminobenzoate (Glyceryl PABA) UV Protective Sunscreen Raw Material-CAS 136-44-7

• Glyceryl P-Aminobenzoate, commercially known as Glyceryl PABA, is a high-purity cosmetic grade semi-water-soluble UVB filter refined by advanced esterification reaction, purification and recrystallization technology.

• It is a gentle and widely used core functional raw material in the global high-end sunscreen and personal care industry, derived from PABA (para-aminobenzoic acid) and modified by glycerol esterification to improve its mildness and compatibility.

• Different from traditional water-soluble PABA with strong irritation and poor photostability, ordinary oil-soluble UVB filters with heavy texture and poor compatibility with mild formulas, and common semi-water-soluble sunscreen agents with low absorption efficiency, Glyceryl PABA has a unique glycerol and p-aminobenzoic acid ester structure, which is a typical mild semi-water-soluble UVB absorber.

• It can efficiently absorb ultraviolet rays in the 280-320nm band, with a peak absorption at 308nm, forming a thin and breathable protective barrier on the skin surface to effectively resist UVB radiation damage, prevent skin sunburn, redness, itching and long-term photoaging problems such as fine lines, pigmentation and skin roughing. As a multi-functional sunscreen raw material integrating UV protection, formula synergism and mild care, it not only has excellent UVB absorption capacity, but also can act as a synergist for other mild UV filters (such as Zinc Oxide, Titanium Dioxide and Octocrylene), improving the photostability and SPF value of other sunscreen agents, avoiding their decomposition under sunlight, and extending the effective protection time of sunscreen products, especially for sensitive skin and infant care formulations.

• It is pale yellow waxy semi-solid with good semi-water solubility, can be quickly dispersed in both water and oil phases of cosmetic formulas, has good compatibility with various mild cosmetic raw materials, will not cause heavy, greasy or sticky feeling on the skin, and will not leave white residue on the skin surface, bringing a soft, smooth and comfortable use experience.

• The product has excellent chemical stability and photostability, can be perfectly compatible with various cosmetic raw materials such as mild emulsifiers, plant extracts, humectants and functional active substances, no precipitation or delamination, no oxidation, discoloration or peculiar smell during long-term storage and normal processing, ultra-mild and non-irritating, non-sensitizing, non-comedogenic, no harmful impurities such as heavy metals, passed multiple skin safety tests (including sensitive skin patch test) and cosmetic raw material safety certifications, suitable for sensitive skin, dry skin, infant fragile skin and maternal skin, and is the core raw material for creating mild, non-irritating and gentle sunscreen cosmetic formulas, especially suitable for semi-water-based, water-in-oil mild sunscreen products and maternal and infant care products.
